I shouldn’t have to say this, but one needs to be resepctful. Even if you don’t agree with me, it does not mean that I would deserve to be put down, and verbally abused. If you can’t act like a mature person, then we don’t need to keep in touch. If you are abusive over the phone, you would likely get blocked, as I have better things to do than listen to your superiority complex. If you are mature, then you are respectful, and can handle different opinions.
